What is PDF OCR X?

PDF OCR X is a simple drag-and-drop utility for Mac OS X and Windows, that converts your PDFs and images into text documents or searchable PDF files.
It uses advanced OCR (optical character recognition) technology to extract the text of the PDF even if that text is contained in an image. This is particularly useful for dealing with PDFs that were created via a Scan-to-PDF function in a scanner or photo copier.
